    Use SSize_t for tmps stack offsets

    This is a partial fix for #119161.

    On 64-bit platforms, I32 is too small to hold offsets into a stack
    that can grow larger than I32_MAX.  What happens is the offsets can
    wrap so we end up referencing and modifying elements with negative
    indices, corrupting memory, and causing crashes.

    With this commit, ()=1..1000000000000 stops crashing immediately.
    Instead, it gobbles up all your memory first, and then, if your com-
    puter still survives, crashes.  The second crash happesn bcause of
    a similar bug with the argument stack, which the next commit will
    take care of.
